From the The AP (Advanced Placement) Art History Curriculum Framework by the (US) College Board:
This seems to be new. It is copyrighted 2015. Other materials in the AP College Board site refer to Jerusalem as if it does not belong to any country, but only this new document seems to specify "Palestine" as to where Jerusalem belongs.
Interestingly, its 2010 Scoring Guidelines for the same topic mentions facts that students may include when discussing the building, and one of them is "The location is also sacred to Jews and Christians, and so the
dominant position of the Dome of the Rock implies Islam’s spiritual superiority." Naming Jerusalem as part of a fictional Arab state whose constitution says its official religion is Islam, rather than as the capital of the existing Jewish state, implies the exact same thing.
